-Be it known th t-I, HENRY citizen of the" United States, residing at 1 ClevelandQin 'the county of Cuyahoga and Stete'of Ohio, have invented a certain new and useful Improvement in Demountable Rims, of which the following a in, clear,

andexact description,- r'eferencebeing had to the accompanying drawings.

, This invention relates to a one piece tran-. split demountable tire-carrying rim and has for its object'to provideaflsimple means for'cont'racting and expanding the rim as desired, said operating means serving'also as aconnectionbetween the ends of the rim,

holding them against circumferential and I lateral movement.

' 1 IA-notherobject of the invention is to utilize a part of the rim contracting and expand'ing means as a driving lug, and while this invention is particularly adapted for use in connection with demountable tire carrying rims mounted upon channeled sheet metal fixed rims, it can also be used upon wheel bodieshaving the usual wooden telly and metal fixed rim.

I cult to contract or collapse a one piece tranprovide a very simple and highly etlicient 'Heretofore it has been extremely diffi split rim in which the cut has been made axially or in a radial plane, and it is therefore the object of the present-invention to device which not only quickly and easily parts and in the specification Figure 1 is aside elevation of In thejdrawingszforming a 53m of this a tire-carrying rim arranged within a tire and provided with one'embodiment of my invention as a means for opening and closing the said transplit rim. Fig. 2 is a similar view showing the position" of the partsv assumed when the rim is contracted. Fig.

3 is an enlarged view of the rim operating means, and showing the driving lug in connection with the base of a metal fixed rim.

Fig. 4 is a' view, upon an enlarged scale, showing the position the rim ends and connecting-means assume when the rim is congtracted; and Fig; 5 is a detail plan view of the rim ends and the connecting and operat- \1ng means connected thereto.

In the practical embodiment of my in vention'I employ a one piece rim A adapted.

to receive a tire B, and this rim can be either of the straight side or clencher type. This rimis divded or cut transversely at one point as shown at C, this out being straight in an axial direction or in a radial plane, the out being straight through bothvthe sides and the base of the atthe end thereof.

A block or lug E'is connected to the other end ofthe rim and preferably projects beyond the division 0 toward the first mentioned lug or block D, and pivotally connecting-these lugs or blocks D and E is a link F; pivotally connected to the block D o nsane of a pivot pin G, and to the block or lug E by the pivot pin G, and it will be noted that the pivots G and H are both upon the same side of the division 0, and it will also be noted that the center of the pivot G is nearerto the center of the rim than the center of the pivot H. v

The block or lug E projecting beyond": the division or split, of the rim contacts with A lug or block D is rigidly connected to one-rim end adjacent the division C but not the inner face of the opposite end of-the rim and positions the meeting ends of t is rim. The link F is bifurcated at its opposite ends and the lugs or blocks D and E f within the bifurcation and consequently the rim ends are-held against both circumferential and lateral movement at all times.

I The resiliency of the rim tends to hold the parts in their normal positions such as shown in Figsl 'and'iB, and the pivot H- being lower than the-pivot'G, the link}? acts as a toggle, and. consequently, when the parts are in the position shown in Figs. 1 and 3 this tog le, coupled with the resiliency ofthe rim will'falways maintain the parts locked. y A I When however, it is desired to break the lock and contract the rim, the link F is swung back upon the pivot G. and in. order to;

render this operation easy I vprovide the is adapted:

or anal-'- link F with a lug or studs l which tured end of a suitable lever or tool (not shown) and by means of which the link can be thrown overthrough a considerable are tion therewith and carries the parts to the position shown in Fig. 2 and therefore locks the'rim and the connecting means in their opened or contracted positions. If de ired the lever can be removed from the l g or pin I without releasing the parts.

, After the rim has been contracted, and locked in such contracted position as shown in Figs. 2 and 4, it is obvious that the tire can be quickly and easily placed thereon or removed therefrom.

When it is desired to unlock" the parts from their contracted position and return them to their normal or expanded positions it is only necessary to bring the lever into engagement with the stud or pin I and move the same back to the position shown in Figs. 1' and 3, and as soon as the pivot H passes beyond the pivot G in this return movement, the resiliency of'the rim will act to assist in the final operation carrying the pivot H below the pivot G and lockingthe toggle.

This device is preferably arranged upon rims which are intended to be used upon channeled sheet metal fixed rims and ample space is therefore provided within the channeled fixed rim for the lugs and link, and the inwardly projecting lug or stud I is adapted to be projected mto a suitable opening K pro luced in the base of the fixed rim and therefore serves as a driving lug and also prevents any circumferential movement of the rim upon the fixed rim.

Any type of rim fastening devices can be employed for connecting the rim to the wheel body.

It will be thus seen that I provide a very simple means for connecting the ends-of a straight cut one-piece rim said means'being usable for contracting and expanding the nm as desired, and also usable as a driving'lug in connection with the wheel body.

It will also be noted that in addition to the case and rapidity with which the device'can be operated, that, in connection with the resilient rim, itprovides a perfectly safe lock for holding the parts in either an open or Having thus described myinvention, what I claim is z- 1. A one piece tire carrying rim, divided transversely at-one point, lugs connected to said rim ends, one of said lugs projecting beyond the dividing line, and a link pivotally connected to said points of said link being at diiferent dismembers, the piot 1 tances from the center of the, rim, said link being shaped for engagement with means for'turning it upon its inner pivot.

2. A one piece transplit rim, members rigidly connected to said rim upon opposite sides of said split, One of said members projecting beyond said split, and a movable member pivotally connected to said rigid member and having means for engagement witha turning tool, said movable member being turnable upon its pivot remote from the split, said pivot being nearer the center of the rim than the other ivot.

3. A one piece tire carrymg rim transph at one point, lugs connected to the ends of said rim, a link pivotally connected to said lugs, both ofthe pivotal connections being upon the same side of the split, the pivot remote from the split being nearer the center of the rim than the other pivot.
